Full Discussion: X11 forwarding through a tunnel
Operating Systems Linux Red Hat X11 forwarding through a tunnel Post 302895670 by Corona688 on Tuesday 1st of April 2014 05:45:38 PM

This is a bit different than standard X11 forwarding, you'd need to figure out exactly what port numbers you need and put them under 'tunnels'. I think X11 is 6000 but that can vary.

Under 'source port' you'd put 6000, I think. And under destination you'd put remotehost:6000. This means, when you logged into bastion, and connected to localhost:6000 on your laptop, the SSH tunnel would connect to remotehost:6000. So localhost:6000 would effectively be connecting to remotehost:6000.

xkbdfltmap

xkbdfltmap(1X)															    xkbdfltmap(1X)

NAME

       xkbdfltmap - Determine default X keymap for locale and keyboard

SYNOPSIS

       xkbdfltmap [options]

OPTIONS

       lang  specifies a string to be used instead of the console language. This option is useful for locales that cannot be specified in the con-
       sole. This option is only used if XKB is active in the server.  kbd specifies a string to be used instead of  the  console  keyboard.  This
       option  is  useful  for	keyboard types that cannot be uniquely identified by the kernel.  For example, the kernal identifies the Microsoft
       Natural Keyboard as a PCXAL.  If XKB is not active in the server, file specifies the xmodmap command.  The default is /usr/bin/X11/xmodmap.
       If  XKB	is  not active in the server, file specifies the file containing the information necessary to determine what xmodmap keymap to use
       based upon the console language and keyboard type.  The default is /usr/lib/X11/xdm/Xkeymaps.  If XKB is active in the server, file  speci-
       fies  the XKB keyboard compiler.  The default is /usr/bin/X11/xkbcomp.  If XKB is active in the server, path specifies the top-level direc-
       tory that contains the XKB keymaps.  The default is /usr/lib/X11/xkb.  If XKB is active in the server, file specifies the  file	containing
       the  information  necessary  to	determine  what  XKB  keymap  to  use  based  upon the console language and keyboard type.  The default is
       /usr/lib/X11/keymaps.dir.  Specifies whether execute the necessary command to download the keymap  to  the  server  after  determining  the
       default,  or  whether to just print out the necessary command.  Specify -exec to download the keymap. Specify -noexec to just print out the
       necessary command.  The default is -noexec.  If the -noexec command is specified, and XKB  is  active  in  the  server,	the  -file  option
       instructs  xkbdfltmap  to  print  out  just the XKB keymap file that contains the keymap.  A keymap will not be downloaded to the server if
       -file is used.  If the -noexec command is specified, and XKB is active in the server, the -map option instructs	xkbdfltmap  to	print  out
       just the XKB keymap name.  A keymap will not be downloaded to the server if -map is used.

DESCRIPTION

       The  xkbdfltmap	command queries the system console for the language and keyboard settings.  Then, based upon whether the XKB server exten-
       sion is active in the server, it will  optionally  download  an	xmodmap  file  from  /usr/lib/X11/keymaps  or  an  XKB	keymap	file  from
       /usr/lib/X11/xkb to the server.

FILES

       /usr/lib/X11/xdm/Xkeymaps

       /usr/lib/X11/xkb/keymaps.dir
